Harking back a few (very few) years, I can remember asking a number of Aikido experts about the ki skills in relation to the fact that at a minimum both Ueshiba and Tohei demonstrated those skills repeatedly as part of their Aikido. Ueshiba and Tohei never demonstrated MMA or Systema or other "arts that will help your Aikido improve". But for a limited number (as a start) of people to begin understanding how intrinsic these skills that Tohei and Ueshiba demonstrated are a part of Aikido is a pretty good start.

The problem is that (in my opinion) these skills are so intrinsic to Aikido that it's impossible (or absurd) to relegate them to "other" types of discussions. Ultimately, as more people become aware of the obviousness of the conclusions, I think the "internal" problem will go away. If the skills become understood in the full context of not only the abilities, but also the derivations and the breadth of the relationships in the cosmology and quasi-religious, then the "IT" will expand into the forums on 'spiritual', 'training', and so on. I.e., all we're watching is a work in progress, not a static situation.
